Meeting notes Sept 12

  • New attendees in the invite list

    • Sangshetty Patil (AMD San Jose, monitoring)

    • Sean Keys (Android Auto all things Virtulization)

  • Bill has started a Demo and CI project for all the individual demos

    • https://github.com/wmamills/hvac-demo

    • Viresh’s kernel demo is there and works with 100% automation

    • The project builds everything and can run it

    • Bill is in the process of adding Edgar’s demos from here

    • Happy to rename the project if we want to broaden the scope to all of virtio-msg but need owners for the write up of each demo to be added. (Like Viresh and Edgar did).

    • Plan to enable this as CI

  • Bertrand published his work in Xen for FFA indirect message support

    • Needs kernel work to match but right now no one is available from Linaro

    • Arm is working on kernel side FFA v1.2 target kernel v6.12

    • Working to bring Xen up to FFA v1.2

  • We have created the mailing list virtio-msg@lists.linaro.org

  • Updates from Edgar

    • Xen mediated virtio-proxy?

      • proxy is in xen hypervisor (not public (yet))

      • qemu is doing foreign memory maps and xen events for notification

      • Trying to do something that works with current kernels

    • What is this message-queue thing? It is Gaunha hypervisor specific message passing

  • Updates from Lei?

    • Getting ready to take Google’s Trusty Virtio-msg VSOCK drop

    • Using Viresh’s base

  • Armelle’s updates

    • Trusty drop

      • will be QEMU based drop

      • Will be switching to virtio-msg / FFA

      • The Rust dependecies were a struggle to integrate into TEE environment

    • microDroid VM Update

      • Linux frontend and backend w/ virtio-msg-ffa VM to VM

      • Backend is microDroid w/ RustVMM devices

      • CrossVM

        • Google’s RustVMM based VMM

      • End goal is to have VM to VM

    • What about header files for the messages

      • Desire to dual license the Linux header file at least to start

  • Edgar

    • Spec updates: disable queues, and others.

    • Need to be able to shutdown and bring back up

    • Cleanup & restart after abortive shutdown of either side

    • Graceful shutdown initiated from the device (like eject button on CD)

    • Should we be giving a heads-up to the upstream virtio spec owners?

  • Alex: Viresh has sent a clean-up set of patches defining transport level better
